SIPHON EGG PICKER AND TROUGH CLEANER Filed July 19, 1929 2 Sheets-Sheet 2 In venior Attorney ?atented Feb. 2, 1932 res ' FRED wALoo'r'r, or TROY, MONTANA SIPI-ION PICKER AND TROUGH' CLEANER Application filed. July 19,

The present invention relates to an egg picker and trough cleaner operated by siphons, and has for its prime object toprovide means whereby to facilitate the picking of un-' fertile fish eggs from those that are fertile.

Another very important object of the invention resides in the provision of an appara tus of this nature which may by a certain change be converted into a trough cleaner.

A still further important object of the invention resides in the provision of an apparatus of this nature which is simple in construction, inexpensive to manufacture, strong and durable, thoroughly efhcient and reliable in use, and otherwise well adapted to the purpose for which it is designed.

Numerous other objects and advantages of the invention will appear as the description proceeds, and a clear understanding of the invention will be obtained from a study of the following description, taken in connection with the accompanying drawings, wherein:

Figure 1 is a side elevation of the apparatus embodying the features of my invention. Figure 2 is a perspective view of the inlet conduit.

Figure 3 is a perspective View of the screen tube.

Figure at is a sectional View through the screen tube and the coupling member for securing the tube to the siphon tube.

Figure 5 is a sectional view through the apparatus. v

Figure 6 is another perspective view of the inlet conduit showing particularly the upper end.

Figure 7 is an end elevation of the bulb. Figure 8 is a perspective view of the bowl. Referring to the drawings in detail it will be seen that 5 denotes a-glass bowl with an externally threaded neck 6 at the upper end thereof, while the numeral 7 designates a rub berbulb having an internally threaded neck 8 depending therefrom for engagement over c the neck 6. An inlet neck 9 projects from one end of the bulb and an outlet neck 10 projects from the other end of the bulb.

A glass tube 11 has an upper curved end 12 insertable through the neck 9 and has an opening 1 1 in the bottom of its inner extrem- 929. Serial No. 379,557.

ity and at the bottom end of the glass tube llis formed a fan-shaped intake seat 15.

As shown in Figures 3 to 5 inclusive the invention further comprehends the provision of a suitable coupling member designated generally by the reference character 16. The tubular coupling 16 is provided at opposite ends with enlarged heads 17 and 18 respectively. The heads 17 and 18 forming the shoulders 19 and 20 respectively. Intermediate the shoulders 19 and 20 th-e'tube is provided on its outer periphery with a circumferentiallyextending flange or collar 21. Be-

tween the respective heads 17 and 18 and the collar 21 the coupling 16 is further provided with circumferentially extending. beads 22{22. 7 v A tubular screen 23 is perforated as indicated at 24, and at one end of the tubular screen the same is externally threaded as at 25 and has its threaded end 25 threadedly en-- gaged within the head 17 of the coupling 16 as indicated to advantage in .Figure 4. In practice, they forward end of the coupling 16 is inserted through the outlet neck 10, the material forming the neck 10 being of rubber, will of course grip the said end of the coupling 16' at the shoulder 19 and the bead 22, the outer end of the neck 10 abutting against the adjacent face of the collar 21 thus securely -maintaining the" coupling member within the neck. The screen 23 projecting forwardly from the head 17 extends through the bulb 7, the inner of which is in opposed relation with respect to the inner end of the glass tube 11, as shown toadvantage in Figure 5.

A siphon hose 26 has one end thereof engaged over-the head 18 and. bead 20 of the coupling 16, said one end of the siphon hose 26 abutting the adjacent face of the collar 21 as also shown to advantage in Figure 5. Thus it will-be seen that the coupling 16 proa videsv a secure connection between the screen 23 and the siphon hose 26, and also provides an unrestricted passage between said tube screen 23, and the siphon hose.

There a continuous flow of water through the apparatus because of the siphon arrangement and therefore the eggs will be drawn through the glass tube 11 and collected in the lass bowl or reservoir and there 1s complete control because of the siphon hose 26 and associated with the lower portion thereof 1 provide a clamp 27, or in lieu of the clamp, the finger and thumb may be used for this purpose so as to shut off the Water and hold, the eggs in any desired position;

If a fertile e is picked 113 into the lass tube it can, by shutting off the flow ofwatr to a fixed point, he ejected-ifrom'theglass tube by a sli ht pressure on the bulb, and then, of course, the glass "tube is setback in the trough and the bulb released which will suck up suflicient water to continue'th'e flow: illhen it is desired, through the medium of the coupling '16, the's'creen 23'ma'y be readily withdrawn from the interior-of the bulb 7,130- getherwiththe coupling16, orthe screen 23 may beremoved, in an obvious manner without 'disturbingthe"couplingl6 or the hose 26 secured thereto. v

It is th'oug'ht that the construction, operationutility and advantz'iges *ot'this invention will nowbe quite apparentto those skilled in this art without a more detailed description thereof. 7

The preferred embodiment of the invention has been disclosed inconsiderable detail mere lyfor the purpose of exen'iplification, since in actual pi-"actiee' it attains the ieatures'ofad vantage enumerated as'desirable'in the-statement of the invention and the above descrip tionz' Even though I have herein shown 'anddescribed the preferred embodiment 'of-myin vention, itis to'be understood that'the same issusceptible'to changes fully comprehended by the spirit of theinventionasherein de: scribed and the'scope of theapp'e'n'ded claims.

l-Iaving thus'described my invention, what I claim "as new is: v

1. An apparatus of the class described comprising a receptacle, a bulb connected to andmounted on the receptacle, a glass tube leading into the bulb, anda siphon connected with the bulb, said siphonconnection'com prising a tube extending into"the"bulb, and havingits axis at right angles to the vertical axis'iof-the receptacle, said last mentioned tube being perforated, an'dmeans for'con necting one endofsaid'last mentioned tube with a siphon hose.

' 2. An apparatus of the class described comprising a receptacle, a bulb connected to and mounted on the receptacle, a glass tube leading into the bulb, said tube having its upper 'en'dcurved and its lower end'inthe term of a widened funnel, a perforated tube leadinginto the bulb from the opposite end of the bulb, and having its axis approximately parallel to the longitudinal axis of the bulb, a tubular, coupling membermounted inthe bulb at one end of the bulb, means for con necting said last mentioned tubular member with one end of the coupling member, said coupling member having its opposite end extending exteriorly of the bulb, and means for securing a siphon hose to said last mentioned end of the coupling member.

3. An apparatus of the class described comprising a receptacle, a bulb connected to and mounted oir-the receptacle, aglass tube leading into the bulb, said glass tube projecting'inwardly of the bulb and having an open-i'ngain' the'bottom of its inner extremity, said glass tube having its lower end in the farmor "a widened fii-nnel, a tubular coupling member removably secured in the bulb at one end of the bulb",- a perforated tube threaded in said couplingmember at one end of-the co'uplingjmeniber and extendin inwardly of the bul'b,' anjda siphon hosesecured to the other lild-bflsald coi'ipl'in'g-member ex'triorly ofsaiol'bulbi I I p v In testimony whereof I mysignature.
